I’ve been using codepen to create a project in the form of a pen, and everything has been going fine until everything froze. I’ve tried reloading the page, opening in a newtab/window and restarting chrome, but the pen just won’t load. I tried exporting and running with notepad, but that had about 3 hours less of what I had done. Is there anything I can do to recover my work? And if not what caused this error?

If you are getting a message such as ERR_BLOCKED_BY_CLIENT, it is probable that something on your computer (client) is blocking it. This is most likely an adblocker or some other web filter. If you have an adblocker, try disabling it on codepen. Other than that, try a different/newer browser and clear your cache.

OMG! I made the mistake of storing my code in CodePen, then when I pasted something over the wrong project, there was no UNDO button! Eek! Had to redo the entire project from scratch and resubmit! Ok, folks. Lesson learned. I’m doing the coding on a local app (Komodo - it’s free), then when I’m happy with my project, copy it to CodePen for viewing by the FCC gurus.
Glad someone was able to view some of it and get it to you so you didn’t have to start from scratch as I did. Yay!
